Maximum output frequency is 133.33 MHz — enough for most DDR, Ethernet, or FPGA reference clocks in the 100–133 MHz range. Supply voltage spans 3V to 3.6V, so it runs cleanly off a 3.3V rail without an extra regulator. ## 8-SOIC footprint, commercial temp range Housed in an 8-SOIC (0.154\", 3.90mm width) — a standard 150-mil SOIC that routes easily on two-layer boards and fits most pick-and-place feeders without a nozzle change. Input and output are both single-ended clock signals; no differential pair needed, which simplifies layout on cost-sensitive designs. ## Active production — no LTB on the horizon ROHS3 compliant, so it passes the material declaration for EU and most global markets without an exemption expiry concern.","metaTitle":"CY2305ESXC-1HT Zero Delay Buffer – Infineon 133 MHz 8-SOIC","metaDescription":"CY2305ESXC-1HT from Infineon: Zero Delay Buffer, PLL with bypass, 1:9 fanout, 133.33 MHz max, 3V–3.6V supply, 8-SOIC, active production.
